Recently i got hammer engine to make maps a bit better than previous ones that gave the results of uglyness, i can set up things, build up walls, place prop_statics but when i get to files and press "Run map" it opens the command prompt but after a split second it closes without opening, i have seen people with the same problem but as my english is epic awesome and im not the most computer man i couldn't figure anything, i seen some tutorials but not with the issue.
Into the problem a bit more it goes like this: click files, click run map, opens the little menu, i configure it all to normal, and press ok
anyone with the same issue or any solutions?
